.TOJLZZ whom if may concern:

Be it known that I, VILLIAM LUND, a subject of the Queen ot' Great -iritain and Ireland, and a resident of Philadelphia, Pennsylvania, haveinventcd certain Improvements in fool- V\Vashing Machines, of which the following `is a specification. n

My invention relates to that class of woolwashing ni achines in, which the wool is carried through the bowls by means of endless belts, the object of in v invention being to insure a positive and definite feed of the wool by these belts. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a longitudinal section of a woolwashing machine constructed in accordance with my invention. Fi 2 is an enlarged sectional view of part of the same. Fig. 3 is a detached perspective view of one of the parts of the machine. Fig. 4 is a transverse section, on an enlarged scale, on the line l 2, Fig. l; and Fig. 5 is an enlarged plan view of part of the carrierbelt of the machine.

A represents the bowl, which is divided by a central partition into two chambers, A A2, each containing liquid for washing the wool as it is carried along through. the same, the bowl having at one end a feed-apron, B, and at the opposite end a pair of squeeze-rolls, D, while an intermediate pair of squeezerolls E is located abo e the central partition, Cnof the bowl.

In each of the chambers of the bowl is a pair of feedwaprons or belts, F F', the upper apron being of wire-gauze or perforated sheetmetal and the lower apron being slatted-that is to say, com posed of strips jointed together, so as to pass aronm'i the rolls .17, these strips being preferably ot' metal. A iiexible beltor apron of any desired cllaractcrmay, however, be used, although the slatted apron is preferred.

In the opposite sides of the bowi,or in plates secured to the inside ol the same, are formed slot-s lain which travel the opposite ends of bars d, each armed with rows of teethf, which project through openings in the slats oi' the lower aprons, l", as shown in Fig. 2. 'Piet-Ween the opposite rolls carrying the apron these slots b are parallel with said apron, and are so located in respect thereto that the teeth f are caused to project above the surface of the apron and to or into the interstices of the upper apron, F, so that the wool fed onto the receiving' end of the apron F is caught and fed forward by the teeth and is held thereon by the contact or engagement of the upper wire-gauze or sheet-metal apron with said teeth, so that a positive and definite forward movement of the wool through the liquid in the bowl is insured, the wool being carried along near the surface of the liquid and kept up out of the dirtv and sediment which collects in the bottom of the bowl.

The roll :r at the delivery end of each apron F has a number of radial slots, g, as shown in Figui?, and at points adjacent to this roll the slots h are made cam-shapeifl, as shown by dotted lines in said Fig. 2 hence as the toothed bars CZ approach the delivery end of the apron F they will be retracted and their teeth will be drawn through the openings in the slats of the apron, so that the points of the teeth will not project above the surface of the apron and will not interfere with the free delivery7 of t-he wool therefrom, the teeth being projected again by the action of the cam-slot upon the bars d in time to catch and carry forward the wool placed upon the apron at the receiving end of the same, the projecting of the teeth being preferably eifected as soon as they have passed below the center of the roll at the delivery end of the apron, as shown.

From the first pair of aprons the wool is delivered by a short carrierapron,G, to the intermediate press-rolls, and after being squeezed thereby is delivered to the second set of aprons, by which it is carried along through the liquid in the chamber A2 and is delivered by a secon d carrier-apron, G', to the final pressrolls D and receives its final squeeze prior to delivery from the machine.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

l. The combination of the carrier-apron and retainer-apron, bars having teeth projecting from the cai'riei'ap1on, rolls for said apron recessed to receive the bars, and cam -slots whereby the bars are retracted and their teeth withdrawn from above the carrier-apron at the delivery end of thelatter, all substantially as specified.
